Holley 4150 HP Carburetor

Holley Model 4150 HP Carburetor - $400

After this last season of racing with it, I can’t complain about its performance, however I still want more. We are planning to run a custom carb, so looking to get some cash to go towards it. This carb ran great on the dyno with 425 HP and 375 ft.tq – to the ground. And propelled our car to a 10.99 in the quarter mile. So don’t think the low (650) cfm can’t perform. Air/Fuel ratios were good until 7200 rpm! This carb is in perfect like new condition with zero modifications. It has very very little street use and according to my time slips only about 40 passes.
